it's amazing! sounds great has a bit of a warm feel to it but that helps with the 702 signatures that I have them hooked up to. The reason why i really want the m40n is due to ease and hdmi arc. It just works! i also have the evo150 here as well
Evo is more clinical and the m40 is more warm but fuller sound. Evo has chromecast built in and the m40n doesn't. Don't let the 70wpc fool you as the AB design really pumps out the power vs the m33 or evo 150. using the app on the phone to match the volume, you have to turn up the volume to 70(m33 and evo) compared to 40 on the model 40.
I tried everything with the m33, it refuses to power on or off with the lg c1 with hdmi arc or earc enabled. That for me is the reason not to buy it.
